Secondly, as the machines and instruments of trade, etc. which compose the fixed capital either of an individual or of a society, make no part either of the gross or of the neat revenue of either; so money, by means of which the whole revenue of the society is regularly distributed among all its different members, makes itself no part of that revenue. The great wheel of circulation is altogether different from the goods which are circulated by means of it. The revenue of the society consists altogether in those goods, and not in the wheel which circulates them. In computing either the gross or the neat revenue of any society, we must always, from the whole annual circulation of money and goods, deduct the whole value of the money, of which not a single farthing can ever make any part of either.
It is the ambiguity of language only which can make this proposition appear either doubtful or paradoxical. When properly explained and understood, it is almost self-evident.
When we talk of any particular sum of money, we sometimes mean nothing but the metal pieces of which it is composed, and sometimes we include in our meaning some obscure reference to the goods which can be had in exchange for it, or to the power of purchasing which the possession of it conveys. Thus, when we say that the circulating money of England has been computed at eighteen millions, we mean only to express the amount of the metal pieces, which some writers have computed, or rather have supposed, to circulate in that country. But when we say that a man is worth fifty or a hundred pounds a-year, we mean commonly to express, not only the amount of the metal pieces which are annually paid to him, but the value of the goods which he can annually purchase or consume; we mean commonly to ascertain what is or ought to be his way of living, or the quantity and quality of the necessaries and conveniencies of life in which he can with propriety indulge himself.
When, by any particular sum of money, we mean not only to express the amount of the metal pieces of which it is composed, but to include in its signification some obscure reference to the goods which can be had in exchange for them, the wealth or revenue which it in this case denotes, is equal only to one of the two values which are thus intimated somewhat ambiguously by the same word, and to the latter more properly than to the former, to the money’s worth more properly than to the money.
Thus, if a guinea be the weekly pension of a particular person, he can in the course of the week purchase with it a certain quantity of subsistence, conveniencies, and amusements. In proportion as this quantity is great or small, so are his real riches, his real weekly revenue. His weekly revenue is certainly not equal both to the guinea and to what can be purchased with it, but only to one or other of those two equal values, and to the latter more properly than to the former, to the guinea’s worth rather than to the guinea.
If the pension of such a person was paid to him, not in gold, but in a weekly bill for a guinea, his revenue surely would not so properly consist in the piece of paper, as in what he could get for it. A guinea may be considered as a bill for a certain quantity of necessaries and conveniencies upon all the tradesmen in the neighbourhood The revenue of the person to whom it is paid, does not so properly consist in the piece of gold, as in what he can get for it, or in what he can exchange it for. If it could be exchanged for nothing, it would, like a bill upon a bankrupt, be of no more value than the most useless piece of paper.
Though the weekly or yearly revenue of all the different inhabitants of any country, in the same manner, may be, and in reality frequently is, paid to them in money, their real riches, however, the real weekly or yearly revenue of all of them taken together, must always be great or small, in proportion to the quantity of consumable goods which they can all of them purchase with this money. The whole revenue of all of them taken together is evidently not equal to both the money and the consumable goods, but only to one or other of those two values, and to the latter more properly than to the former.
Though we frequently, therefore, express a person’s revenue by the metal pieces which are annually paid to him, it is because the amount of those pieces regulates the extent of his power of purchasing, or the value of the goods which he can annually afford to consume. We still consider his revenue as consisting in this power of purchasing or consuming, and not in the pieces which convey it.
But if this is sufficiently evident, even with regard to an individual, it is still more so with regard to a society. The amount of the metal pieces which are annually paid to an individual, is often precisely equal to his revenue, and is upon that account the shortest and best expression of its value. But the amount of the metal pieces which circulate in a society, can never be equal to the revenue of all its members. As the same guinea which pays the weekly pension of one man to-day, may pay that of another to-morrow, and that of a third the day thereafter, the amount of the metal pieces which annually circulate in any country, must always be of much less value than the whole money pensions annually paid with them. But the power of purchasing, or the goods which can successively be bought with the whole of those money pensions, as they are successively paid, must always be precisely of the same value with those pensions; as must likewise be the revenue of the different persons to whom they are paid. That revenue, therefore, cannot consist in those metal pieces, of which the amount is so much inferior to its value, but in the power of purchasing, in the goods which can successively be bought with them as they circulate from hand to hand.
Money, therefore, the great wheel of circulation, the great instrument of commerce, like all other instruments of trade, though it makes a part, and a very valuable part, of the capital, makes no part of the revenue of the society to which it belongs; and though the metal pieces of which it is composed, in the course of their annual circulation, distribute to every man the revenue which properly belongs to him, they make themselves no part of that revenue.
Thirdly, and lastly, the machines and instruments of trade, etc. which compose the fixed capital, bear this further resemblance to that part of the circulating capital which consists in money; that as every saving in the expense of erecting and supporting those machines, which does not diminish the introductive powers of labour, is an improvement of the neat revenue of the society; so every saving in the expense of collecting and supporting that part of the circulating capital which consists in money is an improvement of exactly the same kind.
It is sufficiently obvious, and it has partly, too, been explained already, in what manner every saving in the expense of supporting the fixed capital is an improvement of the neat revenue of the society. The whole capital of the undertaker of every work is necessarily divided between his fixed and his circulating capital. While his whole capital remains the same, the smaller the one part, the greater must necessarily be the other. It is the circulating capital which furnishes the materials and wages of labour, and puts industry into motion. Every saving, therefore, in the expense of maintaining the fixed capital, which does not diminish the productive powers of labour, must increase the fund which puts industry into motion, and consequently the annual produce of land and labour, the real revenue of every society.
The substitution of paper in the room of gold and silver money, replaces a very expensive instrument of commerce with one much less costly, and sometimes equally convenient. Circulation comes to be carried on by a new wheel, which it costs less both to erect and to maintain than the old one. But in what manner this operation is performed, and in what manner it tends to increase either the gross or the neat revenue of the society, is not altogether so obvious, and may therefore require some further explication.
There are several different sorts of paper money; but the circulating notes of banks and bankers are the species which is best known, and which seems best adapted for this purpose.
When the people of any particular country have such confidence in the fortune, probity and prudence of a particular banker, as to believe that he is always ready to pay upon demand such of his promissory notes as are likely to be at any time presented to him, those notes come to have the same currency as gold and silver money, from the confidence that such money can at any time be had for them.
